The LEED Gold<a href="http://inhabitat.com/extraordinary-renovation-of-berlins-neues-museum-wins-2011-mies-van-der-rohe-award/"> fusion</a> of the old and the new has propelled the project into a <em>net-zero energy realm</em>, fit with an efficient shell, passive cooling, natural daylighting and a<a href="http://inhabitat.com/solar-power/"> solar electric </a>array. The project's environmental impact is reduced through a long list of green features that doesn't end at energy performance.

Camden Friends Meeting House (12)

The 150 year old Quaker house, now a small museum, needed structural <a href="http://inhabitat.com/renovation/">improvements</a> and a new place for gatherings.

Camden Friends Meeting House (2)

The design takes advantage of the work by inserting underfloor heating tubing into the old building while it was under renovation.

New but historically accurate windows also help with efficiency.

The annex, adjacent to the original meeting house, is a high performing building that shares the same heating system powered by a<a href="http://www.greenbuilding.com/knowledge-base/what-are-ground-source-heat-pumps"> ground source heat pump</a>.

The roof is made using<a href="http://inhabitat.com/lessons-in-green-building-from-afghanistan%C2%A0/"> SIP panels</a> with a high R-value and no thermal bridging, while the rest of the walls are filled with soy-based expanding foam.

Passive-Cooling-2

The new building is naturally cooled by upper awning windows, which automatically open at night to allow cool air to flush the space.

Camden Friends Meeting House (15)

The windows also allow ample light into the space, which is supplemented by CFLs and<a href="http://inhabitat.com/philips-new-led-bulbs-light-up-the-night-at-inhabitats-green-lighting-holiday-bash/"> LEDs</a>.

Passive-Heating-2

The space is solar heated when the sun shines in the winter, but shaded by overhangs in the summer.

Rain water is captured in a 2,000 gallon tank for toilets and other non-potable uses. What cannot be capture is retained on site with <a href="http://en.wikipedia.org/wiki/Bioswale">bioswells</a>.

The 12.6 Kw <a href="http://inhabitat.com/solar-power/">solar array</a>, while not huge, is more than enough energy for the new building and provides enough to supplement for the historic gathering house making the entire project net-zero energy.
